Why Your Sleep Issues Might Be Hormonal (And What You Can Do About It)

By Dr. C Mac McMillan, Functional Medicine Compounding Pharmacist

If you’ve tried every over-the-counter sleep aid, shut down screens after 9 p.m., and still find yourself staring at the ceiling at 2 a.m., it’s time to stop blaming “bad sleep hygiene.” There’s a deeper issue that too often gets overlooked:

Your sleep issues might be hormonal.

As a functional medicine pharmacist, I’ve worked with hundreds of patients who were doing “all the right things” but still couldn’t fall asleep, stay asleep, or wake up feeling rested. Once we started supporting their hormonal rhythms—especially cortisol, melatonin, and reproductive hormones—they began sleeping like they hadn’t in years.

Hormones: The Sleep Architects of Your Body

Your sleep isn’t controlled by willpower—it’s orchestrated by an elegant system of hormones and neurotransmitters working in rhythm.

Cortisol

This is your “Rise and Shine” hormone. It should peak in the morning and drop steadily at night. But when you’re under chronic stress or inflammation, cortisol stays high in the evening, keeping your brain too alert to rest.

Melatonin

Melatonin is your biological sleep signal. But too much screen time, artificial lighting, and a lack of essential nutrients like magnesium can suppress your natural production.

Estrogen & Progesterone

In women, low progesterone or estrogen dominance can lead to anxiety, restlessness, and night sweats—common during perimenopause and menopause. Progesterone especially has a calming, sedative-like effect when balanced.

Insulin & Blood Sugar

If you’re waking up between 2–4 a.m., it may be blood sugar-related. A crash in the night can trigger cortisol and adrenaline to spike as your body panics to stabilize glucose levels.

Testing vs. Guessing

In functional medicine, we always aim to test, not guess. When patients come to me with sleep issues, we often run simple tests to evaluate cortisol rhythms, melatonin levels, and even estrogen/progesterone balance. We do these!

But even without lab testing, there are foundational nutrients and botanicals that gently reset your hormonal sleep pathways.
